Abstract
In view of the problems such as high labor intensity, low precision, and insufficient intelligence in irrigation control mode of soilless culture in China, a remote irrigation control system was designed for soilless culture. The single chip microcomputer MSP430 was the core of detection and control, and performed the drive control of irrigation components, and combined with corresponding sensors to acquire monitoring parameters of nutrient solution in real time. The upper computer software was designed based on Qt programming to monitor the irrigation status of crops. The software had a number of functions, for example, setting of monitoring values, selection of irrigation modes, real-time display of monitoring parameters, data storage and query of historical data and so on. GPRS wireless transmission technology was used for synchronous data communication between the upper and lower computers. Back propagation (BP) neural network was applied to the regulation of conductivity (EC) and pH values of nutrient solution. The monitoring value regulating experiments show that the system can realize remote stable monitoring and control, the regulation errors in EC and pH values are no more than 0.11 mS/cm and 0.08, respectively.
